Eleven men were reported abducted from the bar on Dec. 17. Such establishments are frequently the targets of extortion attempts.

Two of the abducted men were later found dead.

Police said Monday they found shell casings from assault rifles at the scene, and two handwritten messages whose contents were not disclosed.

Elsewhere in Guerrero, a car ran into a group of people leaving a church Sunday in the town of Ayutla, killing three and injuring four.

Lone officer in Guadalupe abducted
In the Juarez Valley, the only police officer remaining in a string of small border towns has been kidnapped, the El Paso Times reported, citing Chihuahua state officials.

Gunmen stormed into the Guadalupe home of Erika Gandara early Thursday morning and abducted her, said Carlos Gonzalez, a spokesman for the Chihuahua attorney general told the El Paso Times.

Gandara, 28, was the only police officer in the municipality of Guadalupe, which is about two miles from Tornillo, Texas.
